摘　　要：北京大学加速器质谱计的注入系统采用快交替注入技术，注入磁铁分辨率高、强峰拖尾抑制能力强。为提高传输效率、减小分馏效应，在束线设计中采取一系列措施，充分考虑ＡＭＳ的特殊要求。文章给出该注入系统的物理设计与调试测量结果。An injection system with fast switching technique is constructed and put into operation forAccelerator Mass Spectrometry(AMS)measurements at Peking University. The special require-ments of AMS measurement are considered adequatly during the design of beam line. The de-signed features of injection system as well as the measured performance are presented.
